Ubuntu's sudo command is something that I miss when I'm using other distributions. For the uninitiated, when using Ubuntu, you can execute privileged commands as the root user by prefacing them with sudo. This saves having to log in as root, do your work and then log out again (or if you're like me, forget to log out and keep doing things as root). Fortunately, it's a cinch to add the functionality to other distributions such as Debian or Fedora.
